To all whom 'it may concern:

Be it known that I,`LoU1s E. VViaLsi-na citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements in Iiles, of which th following is a specification.

My invention relates to certain improvements in piles of concrete, orpreparatory piles which are driven into the ground and removed so as toallow the opening to be filled wit-h concrete.

The object of my invention is to provide means for properly jetting ashouldered pile into the ground; the jets'of water disturbing the groundat the shoulders as well as at the point of the pile.

In the accompanyingdrawings Figure 1, is a sectional view of ashouldered pile illustrating my invention, the pile in this case beingprovided with an inner and an outer form, the inner form being thedriving form; Fig. 2, is a sectional view illustrating a solid concretepile made in accordance with my invention; Fig. 3, isa sectional viewillustrating a shouldered driving form and a shouldered easing adaptedto be driven into the ground, the driving form being then removed; Fig.4, is asectional View showing the driving form removedand the casingfilled with concrete; Fig. `5, is a sectional view vshowing the innerand outer forms, each made of shells connected together by rings; theouter rings forming shoulders and having jet openings; Fig. 6, is asectional view of a pile in which the outer driving form is made up ofconcreteA shells separated i passageway d extending throughout the bymetallicrings, providing shoulders and having jetting openings at therings; Fig. 7, is a sectional view showing `a pile which can be bothdriven and jettedy simultaneously; the outer form being a continuousshell.

Referring in the lirst instance toFig. 1, A is the out-er form, B is theinner form.

-The outer form has a point a and `a series` of shoulders a', a2/theremay be any number of shoulders, depending upon the lengthof the pile andthe area of its upper surface. The outer form also has inner shouldersupon which rest the flanges b, b, of the inner form, the lower stem ofthe inner form rests on a shoulder b2 at the point of the pile. Formedin the point is a series of jet passages c communicating with a centrallength of the inner form and at the shoulder a are jet passages c in theouterforni which communicate with passages da, in the inner foriu, whichin turn communicate with a passage nl extending to the butt end of thepile, and f, f are jet openings at the shoulders a2 which communicatewith passages cl* in the flange b of the inner form B, and thesepassages communicate with the passage d2 yleading to the butt end of thepile. The flow of water through each of these passages is preferablycontrolled separately by a suitable valve, as illustrated in Fig. 2 forinstance, so that when the pile is driven `the passages d .and d2 arecut off and the passage Z opened until the pile sinks to the lirstshoulder a', then water is admitted to the passage d as well as thepassage d until the pile sinks to the second shoulder a2, then the thirdpassage d2 is opened and the pile driven to theV proper depth. y

I have shown the outer form A made of concrete which may be reinforcedin any suitable manner if desired, and the outerform remains in theground after the inner form is withdrawn and the outer form can be illedwith concrete and reinforcing material, although in some instances ifthe form illustrated in Fig. 1 is used as a preparatory pile and thecharacter Vof the ground will admit of it, the outer forni as when'thepile is not to be withdrawn, thel central passage d in the presentinstance communicates with passages c, c in the head as. which surroundsthe central tube Z and communicates with they 'jet openings e at theshoulder a and the outer passage 2 is formed by a still larger tube andcommuni- Cates with the jet openings f at the shoulder a2. Each of thepipes is provided with suitable valves for regulating the flow ofjetting uid. This pile is jetted into the ground and remains therein7the tubes can be withdrawn if' desired or may remain. as a reinforce forthe pile. A

In Fig. 8, I have shown a shouldered pile The passage d is formed by atube` t', z", vii-'each section z' Aitself 1and tubes g2, gs areattached tothe pile so as to communicate independently with saidpassages, the central tube d, as in the other figures, communicates withthe passa e c in the point of4 the ile.

is made in 'sectons and i2 having inturned flanges' formin shoulders attheir innerends and these anges'stop' shortv of the adjoining section soas to form the jet openings at the shoulders. The'passages g, gcommunicate with the jet openings thus formed so that Huid will beforced 'out at ile to sink.

casing I and `this casing After the casing has reached t e de th desiredthen the form-A2 is withdrawn, caving v the shell I within the ground,as illustrate jet o enings for disturbin Fig. an jetted simultaneously;,water being lso in Fig. 4, and this shellis lled with concrete, asshown in said figure, in .any suitable I'nanner.

In Fig. 5, I have shown. a pile in which the outer form A* is made up ofaseri'es of shells m connected together by shouldered rings n and inthese shouldered `rings are the the ground at the s oulders. The innerorm B' is made up of a series of tubes la connected together by rings kwhich bear upon the inner shoulders of the outer form. The point Chasshoulders upon which the inner and outer driving forms rest and also haspassa es c for the .jettin'g water and an inner tu d communicates withthese openings as sin 1. This form of pile can be both driven a mittedto the 'et openings at the several shoulders as sald shoulders reach thelevel of the ground.

.In Fig. 6, I have shown a construction somewhat similar to Fig. 5, withthe exception that the shells m are of concrete and are vpreferablyloosely connected to the shouldered ring sections n which `havejet fluidpassageways .connected by -pipes leadingto the butt end of the pile. Theinner form B2 is made up of a series of metal tubes k2 screwed intorings 7c which rest against the inner flanges on the ring sect-ion n.

' ders. The inner In Fig. 7, I have shown another form of pile which canbe driven and jetted into the ground;` Inl this pile the outer form a5is made of a continuous tube having shoulders at intervals and et openins at the shoulthe pille, but atthe sev Surv eug'round the earth willroun lng the outer pile A2 is'a thm metallic sho under as` peint andagainst the body of the pile, thus materiallyl il the supportingcapacity of the up e. y

orm 1s ma e similar to the 5, and there is an independent at theshoulders, that' not only cart h disturbed directly under the point ofshoulders m order that-the ile can be readily into the und y jetting,yet w en the -pile is in p ack under the ders as well as increasingWhile I have showntheseveral .zones ben tween the shoulders of an evendiameter throughout, it will be understood that thty may -be taperedand, in some instances,

ile may have, the lower section 4-of an even diameter throughout and theuppersection ta' red without departing p ti features of the invention*I' I claimz- 1. A'pilehaving a plurality of shoulders successivelyincreasing in diameter from the point to the butt, said pile having jetpassages with outlets op downwardly through the respective sho ders,the-outlets at the dierent shoulders from the point. to the butt beingthe center of the pile.-

2. A lpile having form andhaving :fromA the esenmner and outer shoulderssuccessivelyfarther from an inner and an outer" on the outer-form andflanges on the inner..

form bearing upon the inner `shoulders of the outer form, with jetpassages carried by the inner form and communicating with the openingsin the outer form at the shoulders. 3. A pile having a form providedvwith shoulders, and a point, with a casin consisting of a series ofshells 4 flanges -which form shoulders, the said lian es of onesectionterminating short of the dy of the other section so as to form 'etopenings, and means for admitting the jettin iuid to the several jettingope 4. pile ha an outer form with 1nner and outer sho ders, an innerform, said inner form having v upon the inner shoulders` of the outerform, and the outer form having independent jet passages leading to theseveral outer shoulders and to the point of the same, and means forprojectix? jettin Huid to theseveral passages, sai inner orm beingcapable of being driven so that the pile may be simultaneously drivenand jetted into the ground.

In testimony whereof,`I have signed my name to this specification, inthe presence of two subscribing witnesses.
